Nheyo: Mushure mekunge ferromagnetic zvinhu uye maworkpiece aitwa magineti, nekuda kwekuvapo kwe discontinuities, iyo magineti mitsara pamusoro uye padhuze nepamusoro pezvishandiso zvinokanganisa kwenzvimbo, zvichikonzera kuvuza kwemagineti. Magnetic particles akaiswa pamusoro pezvishandiso zvinoshambadzirwa, zvichigadzira anooneka magineti mamaki pasi pemwenje wakakodzera, nekudaro achiratidza nzvimbo, chimiro, uye saizi ye discontinuities.
Kushanda uye zvisingakwanisi:
Magnetic particle inspection inokodzera kuona discontinuity pamusoro uye padyo nepamusoro peferromagnetic zvinhu zvidiki kwazvo uye zvine mikaha yakatetepa (senge makatsemuka anogona kuonekwa muhurefu hwe 0.1mm nehupamhi hwema micrometer) anonetsa kuona. kuona; Inogona zvakare kuongorora zvigadzirwa, semi-yakapedzwa zvigadzirwa, zvakapedzwa workpiece, uye-mu-sevhisi zvikamu, pamwe nemahwendefa, profiles, pombi, mabara, zvikamu zvakakandwa, simbi dzakakandwa, uye zvikamu zvesimbi. Kukanganisa kwakadai sekutsemuka, inclusions, mitsetse yebvudzi, mavara machena, kupeta, kuvharwa kunotonhora, uye kusununguka kunogona kuwanikwa.
Nekudaro, magineti particle tested haigone kuona austenitic Stainless simbi zvinhu uye welds akaiswa austenitic Stainless simbi maelectrodes, uye haikwanise kuona zvisiri zvemagineti zvakaita semhangura, aruminiyamu, magnesium, titanium, nezvimwewo. , uye delamination uye kupeta nekona isingasviki 20 ° kubva workpiece pamusoro.
Penetrant Testing (PT)
Nheyo: Mushure mepamusoro pechikamu chakaputirwa neinopinza ine fluorescent kana mavara dhayi, pasi pechiito che capillary chubhu, mushure menguva yenguva, iyo inopinda inogona kupinda mukati mekuremara kwekuvhura kwepamusoro; Mushure mokubvisa yakawandisa inopinda pamusoro pechikamu, mugadziri anoshandiswa pamusoro pechikamu. Saizvozvo, pasi pechiito checapillary, mugadziri anokwezva akachengetwa anopinza mukuremara, uye iye anopinda anopinda achidzokera mukuvandudza. Pasi peimwe mwenje sosi (ultraviolet kana chena mwenje), mitsetse yeinopinda pakaremara inoonekwa (yellow green fluorescence kana tsvuku tsvuku), nekudaro kuona morphology uye kugovera mamiriro echirema.
Zvakanakira uye zvinogumira:
Kuongorora kwemukati kunogona kuona zvinhu zvakasiyana-siyana, zvinosanganisira simbi uye isiri-simbi zvinhu; Magnetic uye kwete magineti zvinhu; Welding, forging, rolling uye dzimwe nzira dzekugadzirisa; Iine kunzwisiswa kwakanyanya (inogona kuwanikwa iine 0.1 μ M yakakura chirema, ine intuitive kuratidza, kushanda kuri nyore, uye mutengo wakaderera wekuona.
Asi inogona kungoona kukanganisa nekuvhurika kwepamusoro uye haina kukodzera kuongorora maworkpieces akagadzirwa ne porous uye yakasununguka zvinhu uye workpieces ane rough surfaces; Kupararira kwepamusoro chete kwekuremara kunogona kuonekwa, zvichiita kuti zvive zvakaoma kuziva kudzika kwehupamhi hwehurema, zvichiita kuti zvive zvakaoma kuongorora zvikanganiso. Mibairo yekuonekwa inoitwawo zvakanyanya nemushandisi.
